Ghostty 1.4.0发布：首个非Kitty终端完整实现图形协议，性能大幅优化

Ghostty团队于2026年10月27日正式发布了版本1.4.0 1。此次更新历时7个月，由172位贡献者通过2,889次提交完成，旨在显著提升终端模拟器的效率与功能完整性 1。该版本的核心亮点在于成为除Kitty外首个100%完成Kitty图形协议实现的终端，支持动画和相对定位等功能 1。

在性能方面，macOS平台上的I/O吞吐量提高了25%至55%，纯文本下的VT处理速度从128 MB/s提升至约725 MB/s，接近6倍加速 1。内存使用通过透明压缩滚动历史得到显著优化，物理内存占用减少70%至90%，默认滚动限制也从10MB提升至50MB 1。此外，本次更新修复了包括粘贴保护绕过及恶意Kitty图形命令导致崩溃或文件操作在内的多个高危安全漏洞（如GHSA-4hwh-wx3w-3fqg） 1。

系统兼容性方面，Ghostty 1.4.0支持macOS 27 (Golden Gate)，但GTK版本要求升级至GTK 4.18和libadwaita 1.7 1。SSH集成功能也得到增强 1。财务数据显示，开发周期内向签约贡献者支付了$41,820，基础设施花费约为$1,260 1。展望未来，Ghostty 1.5预计将于2027年3月发布，官方已放弃Windows GUI路线图，转而支持下游项目使用libghostty 1。

The Ghostty team released version 1.4.0 of their terminal emulator on October 27, 2026 1. This update marks the completion of a seven-month development cycle involving 172 contributors and 2,889 commits 1. A core feature of this release is the first complete implementation of the Kitty graphics protocol in a terminal other than Kitty itself, supporting both animation and relative positioning 1.

Performance improvements include a 25% to 55% increase in I/O throughput on macOS 1. Virtual Terminal (VT) processing speed for plain text has improved nearly sixfold, rising from 128 MB/s to 725 MB/s 1. Memory usage has been reduced by 70% to 90% through transparent compression of scroll history, while the default scroll limit increased from 10 MB to 50 MB 1.

The release addresses several high-severity security vulnerabilities, such as paste protection bypasses and crashes or unauthorized file operations caused by malicious Kitty graphics commands, including fixes for issues like GHSA-4hwh-wx3w-3fqg 1. Compatibility updates add support for macOS 27 (Golden Gate), require GTK 4.18 and libadwaita 1.7 for the GTK version, and introduce a new GTK rendering pipeline along with enhanced SSH integration 1.

Financially, $41,820 was paid to contracted contributors during the 1.4 development period, with approximately $1,260 spent on infrastructure 1. The team plans to release Ghostty 1.5 in March 2027 1. Additionally, official Windows GUI roadmap efforts have been abandoned in favor of supporting downstream projects that use libghostty 1.
